Title: Method and device for estimating quality of thread
Inventor: AKAGAWA MASATAKE
IPC: D01H13/32
Filed: 1980-09-12
Abstract: PURPOSE: To raise the accuracy of the final inspection and save labor therefor by a method wherein the full-voltage signal of an electric signal for the thickness and mass of thread is dissolved by an amplitude probability density distribution meter and the estimation of quality is conducted in accordance with the form of distribution of voltage of the waveform of frequency distribution.  
     CONSTITUTION: A thread A is passed through a transducer 1 transducing the thickness and mass thereof into electric signals and is made to run. For the transducer 1, a transducer which has a component of electrostatic-capacity or photoelectricity type in the transducing part thereof and can perform the measurement only of an absolute value and a part of change is employed. The thickness and mass of the thread detected through its running are transduced into electric signals, which are introduced into the amplitude probability density distribution meter 4 and dissolved there into the distribution of voltage, and then are indicated by an indicating device B such as Braun tube oscilloscope. By such a constitution, the control based on the peak value of the wave form corresponds excellently to a dyeing spot which is produced when the thread is dyed in a cloth, since the spot is caused by the unevenness of the mass and thickness of the thread. Accordingly, the increase in the accuracy of the final inspection, as well as the labor- savings, can be achieved.

Title: Serial digital video data analyzer
Inventor: STEVEN D MAULER
IPC: H04N9/88
Filed: 1997-05-15
Abstract: PROBLEM TO BE SOLVED: To detect and analyze an error in serial digital video data at a high frequency band. SOLUTION: A video characteristic detection/judging module 12 in a co- processor 10 identifies at least one of a specific characteristic and an error among received video data and a storage means 14 stores the input video data to a cyclic buffer. When the module 12 identifies the specific characteristic or error, the storage means 14 stops the storage. A real time data error analysis module 22 of a microprocessor 20 analyzes the input video data from the storage means 14 in real time to make initial judgement. A static data error analysis module 24 analyzes statistically further the input video data depending on the initial judgement.

Title: Method and device for detecting partial discharge by ultrasonic sensor
Inventor: SASAKI MASAYUKI
IPC: G01R31/12
Filed: 1995-05-25
Abstract: PURPOSE: To positively detect the occurrence of partial discharge by clearly identifying ultrasonic vibration due to the partial discharge. CONSTITUTION: An ultrasonic sensor 3 with a resonance frequency of 30-150kHz is mounted on a cable 1 or a cable accessory to detect ultrasonic vibration generated when a partial discharge occurs. The detected ultrasonic vibration is amplified by a preamplifier 4, is fed to a main amplifier 6 via a band-pass filter 5 with a frequency band of 20kHz-500kHz, and the ultrasonic vibration waveform outputted by the main amplifier 6 is analyzed and observed by a processing part 7 and an oscilloscope 8. By setting the resonance frequency of the ultrasonic sensor 3 to 30-150kHz and the frequency band of the band-pass filter 5 to 20kHz-500kHz, the ultrasonic vibration due to partial discharge and an external acoustic noise can be clearly distinguished, thus positively detecting the occurrence of partial discharge.

Title: Filter for vacuum cleaner
Inventor: OKANISHI SATORU
IPC: B01D47/00
Filed: 1977-10-19
Abstract: PURPOSE: To heighten the restroring property, by preventing the trough part of corrugated filter from getting clogged with fine dusts.  
     CONSTITUTION: The lower end parts 18a of a frame 18 of a corrugated filter material 17 of a filter 5 installed between a dust collecting chamber 15 and a fine dust chamber 16 are alternately displaced with a deviation not smaller than the thickness of the lower end parts 18a coupled to the corrugated filter material 17 so that the trough part of the corrugated filter material 17 does not become drastically narrow. Fine dusts having adhered to the corrugated filter material 17 through a pre-filter 12 are vibrated by a vibrating member 14 so that the fine dusts are separated from the filter material 17. The fine dusts escape into the openings defined by the alternately displaced lower end parts 18a and then slide down into the fine dust chamber 16 without staying in the trough part of the corrugated filter material 17

Title: Atomizing furnace heater for flameless atom extiction analysis
Inventor: SASAKI KIKUO
IPC: G01N21/31
Filed: 1979-09-28
Abstract: PURPOSE:To facilitate a easy setting of the slope heating in the temperature control system, by providing the circuit which multiplies the difference of reference signals between the pre-stage and the present stage of heating by the coefficient adversely proportional to the set time of the present stage, the integral network, the adder and others to a programmer. CONSTITUTION:The output of the temperature sensor D which detects the temperature of the atomizing furnace FN is compared with the reference signal delivered from the programmer PGM. And the sypply of electric power is controlled to secure a coincidence for the above comparison. The programmer PGM of a heater in such temperature control system is constituted by e.g. such circuit as shown in the figure, and then the time setting is given to the timers TM1, TM and TM3 as well as to the temperature of each stage via the potentiometers VR1-VR3 each. Then the timer TM1 works when the time of the DRY period elapses, and thus switches S1 and S2 are turned off and on respectively. Thus the reference signal of the slope heating is generated for the ASH period as shown in the figure. And the relay RY works when the set time of the timer TM elapses to secure the working of the ATM period.

Title: Electrodeless lamp
Inventor: LAPATOVICH WALTER P
IPC: H05B41/24
Filed: 1999-05-06
Abstract: PROBLEM TO BE SOLVED: To radiate light in a relatively narrow blue spectral region with high luminance by including gallium iodide in a lamp sealing substance, arranging it within the inside volume and exciting it by a microwave to emit visible output light. SOLUTION: A lamp assembly 10 is arranged in a reflector 62, a capsule of the lamp is formed from a light-transmitting material as an outside tube 12 and the axis and the inside volume of the lamp are thereby defined. A lamp encapsulant is enclosed in the inside volume. The lamp encapsulant is so composed as to be able to generate strong blue radiation and preferably contains gallium halide, indium halide and the like. The gallium halide is a particularly advantageous ingredient for the encapsulant. In addition, it is preferable that an alkaline metal element is not included in the encapsulant. It is not necessary for arc stability. A power applicator 22 orients a microwave directly toward the capsule of the lamp by receiving a microwave power input and excites light radiation.

Title: Solid-state relay
Inventor: FUKUMORI MINORU
IPC: H03K17/13
Filed: 1987-05-22
Abstract: PURPOSE:To prevent malfunction of a load by providing an integration circuit raising gradually a voltage of a light emitting diode so as to allow a thyristor to be operated again till an initial commutation point of a load current after power is applied to the load. CONSTITUTION:An input current I rises along a charging curve depending on the time constant comprising resistors R5, R6 and a capacitor C2. Since the current conducting capacity of a phototransistor 12 is increased attended therewith, the maximum voltage VZ allowing a thyristor S to be operated rises in proportional to the current condition capacity, said time constant and the value of the input current I are selected to increase the maximum voltage VZ sufficiently till a point of time when a load current is commutated, that is, when a triac T is turned off. Then a sufficient reoperation and refiring time is obtained because the voltage VZ allowing the thyristor S to be operated again reaches a sufficiently high value, even when the phase of the load current IL is retarded by 90 deg. from that of the AC voltage E and the voltage impressed to the thyristor S is raised steeply from a zero volt.
